The facts
What trapiche Emerald actually is
Trapiche Emerald is classified as beryl, with the composition Be₃Al₂Si₆O₁₈. It crystallises in the hexagonal system.
Colour comes from chromium/vanadium in the green sectors; the black spokes are carbonaceous shale and albite inclusions, which is also what a laboratory looks at when it is asked whether a colour is natural.
Refractive index 1.577–1.583. Specific gravity around 2.67–2.78. Cleavage: imperfect basal. Those three numbers separate it from most of what imitates it.
Where trapiche Emerald comes from
Trapiche Emerald is produced at Muzo, Boyacá, Colombia, Peña Blanca, Colombia and Panjshir Valley, Afghanistan.
The locality is part of the description, not a footnote — two stones of the same weight from two of these places are not the same stone.
How trapiche Emerald is treated
Untreated; the six-spoke pattern is a natural growth phenomenon from sectoral crystallisation, not a star. Cut as slices or cabochons. Assembled imitations and painted-back stones exist.
Treatment changes value, sometimes by a multiple, so it belongs in the description before the price and not after the sale.
What trapiche Emerald is confused with
In the trade trapiche Emerald is most often mistaken for, or substituted by, Trapiche ruby and sapphire, Assembled imitations or Star beryl.
The separation is rarely a matter of opinion: refractive index 1.577–1.583 and specific gravity 2.67–2.78 settle most of it in a minute, and magnification settles the rest.
What trapiche Emerald is used for
Demand for trapiche Emerald comes from mineral collecting, jewellery and decorative objects, which is why one price per carat never covers it.
We quote each application in the unit that trade actually buys in, by the specimen, by the carat or by the piece.
Durability and care
Hardness 7.5–8; cleavage imperfect basal. That combination decides what it can safely be set into.
Hardness is not the whole story. Perfect cleavage means the stone can split cleanly if struck along the wrong plane, whatever its Mohs number, so a protective setting matters more here than the hardness suggests.
Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners on anything fracture-filled, stabilised, dyed or visibly included.
What trapiche Emerald costs
As a guide, trapiche Emerald trades around $100–3,000/ct depending on pattern sharpness.
That is a range, not a quote. Colour, size, clarity, cut and origin move the figure a long way inside it, and the only honest price is one given against a specific stone. Send us what you need and we will price it.
Questions
Is trapiche Emerald treated, and how?
Untreated; the six-spoke pattern is a natural growth phenomenon from sectoral crystallisation, not a star. Cut as slices or cabochons. Assembled imitations and painted-back stones exist.
Where does trapiche Emerald come from?
Muzo, Boyacá, Colombia, Peña Blanca, Colombia and Panjshir Valley, Afghanistan. Origin affects price, so we name the locality rather than the country on every quote.
Is trapiche Emerald hard enough to wear every day?
With care. It is 7.5–8 on the Mohs scale, which is hard enough, but imperfect basal cleavage means it can split if struck at the wrong angle. Use a protective setting and avoid ultrasonic cleaning.
How much does trapiche Emerald cost?
Indicatively $100–3,000/ct depending on pattern sharpness. Colour, size, clarity and origin move the price a long way within that, so treat it as a range and ask for a quote against a specific stone.
What is trapiche Emerald confused with?
Most often Trapiche ruby and sapphire, Assembled imitations and Star beryl. A refractive index of 1.577–1.583 and a specific gravity near 2.67–2.78 separate it quickly.
What is trapiche Emerald used for besides jewellery?
mineral collecting and decorative objects. Each of those trades buys it in a different form and a different unit.
